摘要：
In order to improve the chucking performance of a wedge-type power chuck with three top jaws, bending tests, chucking accuracy tests, and cutting tests in the chuck-work system were performed using top jaws with different inner diameters, gripping positions, and taper angles. Bending stiffness, eccentricity of a workpiece, and cutting stability of the chuck were assessed using variance analysis. The inner diameter and the taper angle are effective to increase the bending stiffness; however, the gripping position is generally ineffective. With respect to the chucking accuracy, the effects of the inner diameter and the taper angle are significant; however, the effect of the gripping position is insignificant. Top jaws with tapered gripping parts are effective for limiting chatter vibration in actual use. Therefore, for the wedge-type power chuck used in the experiment, the use of the top jaws with tapered gripping parts is the most effective.
